NEV YORK.

Y., A CORPORATION OF VENTILATING DEVICE SPECIFICATION forming part ofLetters Patent No. 793,403, dated June 27, 1905.

Application filed June l, 1904i. Serial No. 210,662.

To all whom, it may concern:

Be it known that I, Ross TAYLOR, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in VentilatingDevices; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in the meansfor ventilating railroad-cars and other vehicles, ships, and othermoving Structures, and is also applicable to houses or other stationarystructures when the natural air-currents are sufficient to produceinduced currents through the structures.

My invention has for its object simplicity and economy of construction,ready adaptability to the purpose for which it is intended, and wherebyfresh air divested of dust and other heavy bodies may be injected intothe compartment to be ventilated and the vitiated air at the same timewithdrawn from such compartment.

With these ends in view my invention consists in the details ofconstruction and arrangement hereinafter moreY fully set forth.

In order that those skilled in the art to which my invention appertainsmay fully understand the same, I will proceed to describe theconstruction and arrangement of my improved ventilating devices,referring by letters to the accompanying drawings,in which- Figure 1 isa detail elevation of the roofdeck of an ordinary railroad-car with myimproved devices connected therewith. Fig. 2 is a horizontal sectiontaken on the line 2 2 of Fig. 1. Fig. 3 is a vertical section taken onthe line 3 3 of Fig. 1; and Fig. A is a central horizontal section ofthe outside deiiector, but showing a modification in the constructionthereof.

Similar letters of reference indicate like parts in the several figuresof the drawings.

A represents the main roof of the car, and B the upper or deck roof,supported upon the vertical sides or walls C, and in which are usuallyarranged the ordinary ventilatorsashes.

At suitable distances apart openings D are formed in the vertical wallsC, and in said openings are located frames or sashes E, which arepreferably provided with louver-boards F, although such louverboards maybe dispensed with and wire-gauze or other suitable screens may besubstituted therefor'. Intermediate of the openings D and upon the outersurface of the walls C are attached by screws a or otherwise deflectorsconsisting of a rectangular box or frame E', composed of sheet metal orother suitable material, and deiiectorplates FQ arranged back to backand having their outer faces dish-shaped, the upper and outer verticaledges of said plates being curved or bent at an angle to the main bodyportion to produce this effect.

The box or frame E is formed with openings Gr in its top, bottom, andside for the purpose hereinafter explained. plates are bent or returnedat a right angle to coincide with the inner face or side of the box orframe E and are secured thereto by screws or rivets I) or in any otherdesirable manner, and the extreme edges are turned rearwardly toconstitute vertically-disposed guards H, which guards preferably trendoutwardly from the top toward the bottom, as clearly shown at Fig. l;but they may, if desired, trend in a vertically-straight direction. Thebox or frame E may be dispensed with, if desired, and in such event thedeiiector-plates F are then secured directly to the wall C.

The guards H instead of being formed integral with the deiiector-platesmay be formed independently thereof and secured in any desired positionby screws or rivets, or, if deemed not to be absolutely essential, theymay be entirely dispensed with.

On the inside of the openings D are arranged current-deiiectorsconsisting of aplate or board I, having secured to its ends triangularpieces J. The ends of these deflectors are pivoted or hinged, as shownat K, Fig. 3, about centrally of the openings D, and said deliectors areprovided with a suitable knob or handle L, by means of which they may beturned upon The deflectortheir pivots or hinges in order that they maybe placed in positions shown in solid and partly in broken lines, sothat the air entering or discharging through the openings D maybedirected in a plane either above or below the plane of the pivot orhinge of said deflectors, and consequently, the ingoing and outgoingcurrents of air moving in different planes or atdifferent altitudes, amore perfect circulation is obtained.

Instead of placing the defiector-plates F back to back and in contactwith each other, as shown most clearly at Fig. 2, they may be placed ininclined relation, as shown at Fig. 4, to accentuate the deflection ofthe air-current.

Having described the construction and arrangement of my improvedVentilating devices, I will now explain their action.

Assuming that an ordinary car is equipped with the Ventilating devicesand that it is traveling in the direction indicated by the arrow X atFig. 2 and that the pivoted deflector on the interior of the advanceopening D is in the position shown in solid lines at Fig. 3 and that thesimilar defiector on the interior of the rear opening is in the positionshown partly in dotted lines at Fig. 3, the air will strike the face ofthe dish-shaped deflector-plate Fand be deiiected and caused to enterthe advance opening D, as indicated by the arrow Y, Fig. 2, and theinterior deiiector being in the position described the current ofing'oing air will be directed upward toward the deck-roof or ceiling B.Behind the deflector-platcs Fl a partial vacuum is produced, andconsequently the vitiated air within the car, which occupies a lowerstrata than the fresh air taken in at the advance opening, escapesthrough the under side of the interior pivoted deflector, as shown bythe arrows a, the position of the interior deector preventing the escapeof the fresh air.

, When the box or frame E and guards H are employed, the air strikes thedeflector-plate F, and any solid matter, such as cinders or dust, heldin suspension in the air is arrested by the deflector-plate F, a partfalling by gravity through the opening in the bottom of the box orframe, a part passing out through the similar openings G, and theremainder is intercepted by the guard H and falls by gravity.

It will of course be understood that if the car is moved in a directionopposite to that described the deectors will operate reversely.

While I have described the operation ofmy improved devices in connectionwith a moving vehicle, it will be readily understood that they may beusedin connection with stationary compartments when the naturalaircurrents have a velocity suiicient to produce the results described.

Many changes may be made in the details of construction withoutdeparting from the spirit of my invention, which resides in combiningwith the exterior deector arranged between two openings leading into thecar or apartment to be ventilated anQ interiorly-arranged deiiectoradjustably connected with said openings.

What I claim as new, and desire to secure by Letters Patent, is-

l. rIhe herein-described means for ventilating a car or othercompartment, consisting of an exterior projecting air-deiicctorhaving aclosed back and located between two adjacent and separated openingsthrough the wall of the car or compartment, and adjustable deiectorsarranged upon the inside of each of the-said openings, whereby fresh airmay be conducted through one of said openings into the interior of the'car or compartment, and vitiated air withdrawn through the other ofsaid openings, substantially as set forth.

2. In combination with a car or other compartment having adjacent,separated openings in the wall thereof, a projecting deector having aclosed back and located between said openings, andhorizontally-adjustable deiectors arranged upon the inside of each ofsaid openings, and adapted to direct ingoing and outgoing currents ofair in different and independent horizontal planes, substantially ashereinbefore set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
